I removed the carpet and discovered particle board. In the photo, I have removed a piece of the particle board. I plan on installing the ¾ inch hardwood on the subfloor. You can see the hardwood just stick above the baseboard by ¼ inch. How should I do the job?
Butt against the baseboard and install quarterround.
Or get a cutter that cuts that ¼ inch so the hardwood goes underneath, then add quarterround.
